The LTC4000 supports intelligent PowerPath control. An external PFET provides low loss reverse current protection. Another external PFET provides low loss charging or discharging of the battery. This second PFET also facilitates an instant-on feature that provides immediate downstream system power even when connected to a heavily discharged or short faulted battery.

The LTC4000 is available in a low profile 28-lead 4mm × 5mm QFN and SSOP packages.

DC1830B-A

Demonstration circuit 1830B is a battery charger controller and PowerPath™ manager featuring the LTC4000. This board should be connected to a front end DC/DC power supply for a complete charger solution.
